Hi vaibhav4, you should be able to use do_shortcode() with this, link below, but I will definitely take into consideration creating a template tag to use with it as well.
Off the top of my head, I could see possibly setting it up as the_smsc(‘service’, ‘username’, ‘link text’) which would echo, or get_the_smsc(‘service’, ‘username’, ‘link text’) which would return, following WordPress’ example. I don’t know if I’d want to set up a template tag for each service, as that’d get long and require the user to remember too many sites, and I’d have to accommodate for too many unknown factors.
Thanks for the feedback though 🙂
